All of them were due to equipment in one way or another, but due to proper muzzle control no one was hurt.

My first was YEARS ago. Single action revolver. I was young and didn't know how light of a trigger pull it would take. I barely palmed the gun and it went off.

My second was a stuck firing pin on an old SKS I had. Apparently they are somewhat notorious for getting those, and I had a round that didn't chamber all the way so I tapped the bolt. It went forward only to fire the round in there and the one after it. I decommissioned that rifle after that.

The third was I was out shooting a pig, and the lever action I had, had a funky hammer. It slipped off my thumb when I was de-cocking it.

As I said in all cases, muzzle control was the saving factor.

I am thankful for my mentors who trained me well and instilled a healthy fear of firearms.
